Why would you have thought that? What would you be basing it on?
It's a question about relevance - why you decided to bring this up and what you understand about what you decided to bring up.
Has it - even when it produced them in Chechnya?
None of that odd reply from you to to elbows seemed to have anything to do with the link he provided.
There are a number of sources that place jihadis from the Russian federation at the centre of Islamist rebels and in numbers that dwarf other nations.
To spell it out - this is relevant because (i) the jihadis are technically Russian and (ii) the Russian Federation has just started bombing them.
So to say that it is a joke and propagandistic to state that the entrance of the Russian Air Force into the civil war might, just possibly, produce more Russian jihadis is not really that controversial from my point of view...
